Free Space Optics
Taara
By using light beams, improvs the global access of fast and affordable internet.

Introduction
This initiative aims to offer high-speed internet to underserved communities without needing major digging or line construction. Essentially, free space optics is the use of light beams to convey high-speed data between points A and B. It is now being implemented in the Indian state of Andhra Pradesh.
Challenge
Increasing internet access will require the development of cost-effective, dependable, and scalable infrastructure.
Global internet traffic is expected to increase by 24% every year. This increase in demand may be met by fiber-optic cable, however deploying a large fibre network typically results in implementation issues. Planning and excavating trenches to install lines may be time-consuming and expensive, and difficult terrain can provide physical hurdles that make expansion practically impossible. Because of the challenges in installing fibre in some areas, there is a large difference in mobile internet speeds between the fastest and slowest countries.
During the course of working on Project Loon, a potential solution to this problem appeared. The Loon team needed to devise a method for establishing a data link between balloons that were flying over 100 kilometres apart. The researchers looked at using wireless optical communication technologies to create high-throughput networks between balloons. Wireless optical communication, like fibre but without the connections, uses light to deliver high-speed data between two sites.

After some early success in the stratosphere, the team began to explore if it might be able to apply some of that technology to solving connection difficulties closer to Earth.
Taara uses light to transfer information at ultra-high rates through the air as a very thin, invisible beam, similar to fibre but without the connections.

Journey
Extending high-speed, broadband connectivity to the unconnected
Taara’s technology has been tested in India and Africa. Taara connections are a low-cost, quick-to-deploy solution for bringing high-speed access to rural places. Taara connections bridge important gaps between major access points, such as cell towers and WIFI hotspots, and have the potential to enable thousands of individuals get access to the web’s educational, commercial, and communication benefits.
Design
High-throughput links move data wirelessly
• Flexible Technology
Wireless optical communication technology can send data at high speeds of up to 20 Gbps with a clear line of sight. A single link can span up to 20 kilometres and be used to extend fibre networks.
• Long-Range
Long-distance line-of-sight data transfers of up to 20 km.
• High-Speed
High-throughput data speeds range from 10 to 100 Gbps.
• Connectivity Across Terrains
The technology works well in regions where fibre lines are difficult to connect. These include areas near woods, bodies of water, railway tracks, or property with high real estate expenses.
• Easy to Integrate
Based on open standards, it is designed to integrate smoothly with current infrastructure and ecosystems.
Today
Bringing the internet to underserved locations
The Taara team is currently concentrating on offering 20+ Gbps bandwidth over lengths of 20+ km between each terminal, as well as making the units quick and simple to deploy for partners. The team is in discussions with telecommunications companies, internet service providers, and governments all over the world about the potential for wireless optical communication technology to significantly accelerate the deployment of the extensive, high-throughput networks required to support the web’s future.
